Real-World Examples

The TAPA repo also includes a set of large scale designs under the regression directory. This directory is in active development and we are adding more sophiticated TAPA designs here.

  • cnn and lu_decomposition are both systolic arrays (of different shape) originally published in FPGA'21.
  • hbm-bandwidth can be used to profile the HBM bandwidth. It reads from and write back to all 32 channels of HBM. It is a good demonstration of the expressiveness and the optimized area of async_mmap.
  • hbm-bandwidth-1-ch only reads from and writes to one HBM channel.
  • serpens is a sparse matrix-vector multiplication published in DAC'22. We provide different versions that are of the same architecture but different parallelism.
  • spmm is a sparse matrix-matrix multiplication published in FPGA'22
  • spmv-hisparse-mmap is another sparse matrix-vector multiplication published in HiSparse at FPGA'22
  • knn is a K-nearest-neighbor accelerator originally published in FPT'20
  • page_rank is an accelerator for the Page-Rank algorithm that is included in FCCM'21
